Wow, it sure seems like some compilers can't implement isnan() and
friends in a way that pleases themselves!
Fixes bug 22915. Bug trigged by 0.2.8.1-alpha and later; caused by
clang 4.
We need to keep these around for TAP and old-style hidden services,
but they're obsolete, and we shouldn't encourage anyone to use them.
So I've added "obsolete" to their names, and a comment explaining
what the problem is.
Closes ticket 23026.
Closes bug 22964. Based on Teor's replacement there, but tries
to put the comment in a more logical place, and explain why we're
actually disabling compression in the first place.
There isn't much of a point of this buggy test afterall to add twice the same
service object but with a different key which ultinately can end up failing
the test because 1/N_BUCKETS of probability that we end up to put the service
in the same bucket.
Fixes#23023

Fix for 22924. Bugfix on 0.2.9.1-alpha when the test was introducd
-- though it couldn't actually overflow until we fixed 17750.
Additionally, this only seems to overflow on 32-bit, and only when
the compiler doesn't re-order the (possibly dead) assignment out of
the way. We ran into it on a 32-bit ubuntu trusty builder.
Clang didn't like that we were passing uint64_t values to an API
that wanted uint32_t. GCC has either not cared, or has figured out
that the values in question were safe to cast to uint32_t.
Fixes bug22916; bugfix on 0.2.7.2-alpha.
It makes more sense to have the version in the configuration object of the
service because it is afterall a torrc option (HiddenServiceVersion).

The added function frees any allocated pointers in a service configuration
object and reset all values to 0.

As per nickm suggestion, an array of config handlers will not play well with
our callgraph tool.
Instead, we'll go with a switch case on the version which has a good side
effect of allowing us to control what we pass to the function intead of a fix
set of parameters.

Add a helper function to parse uint64_t and also does logging so we can reduce
the amount of duplicate code.

This tests our hs_config.c API to properly load v3 services and register them
to the global map. It does NOT test the service object validity, that will be
the hs service unit test later on.
At this commit, we have 100% code coverage of hs_config.c.

Every hidden service option don't apply to every version so this new function
makes sure we don't have for instance an option that is only for v2 in a v3
configured service.
This works using an exclude lists for a specific version. Right now, there is
only one option that is not allowed in v3. The rest is common.

Try to load or/and generate service keys for v3. This write both the public
and private key file to disk along with the hostname file containing the onion
address.

This also adds unit test and a small python script generating a deterministic
test vector that a unit test tries to match.

This commit adds the support in the HS subsystem for loading a service from a
set of or_options_t and put them in a staging list.
To achieve this, service accessors have been created and a global hash map
containing service object indexed by master public key. However, this is not
used for now. It's ground work for registration process.
